The disk 1 and Disk 2 inputs were designed for a moving iron vinyl record cartridge and it applies an RIAA equalisation curve to th e signal. That is why the CD was very bassy. The CD player has a "line" out put level and should have been plugged into into Tuner 1 or Tuner 2 inputs. One of tuner inputs has a slide switch on the back panel to change the sensitivity of the input, try switching to the lower sensitivity.
